Looks like an awesome time. I can't wait to get back to Colorado.
What kind of DSLR are you using? You said you are new with it right? The pics could be a little sharper. Obviously the action shot of your buddy is a bit more advanced (I could give you some tips on how to try and make them sharp) but the stationary ones could be sharper. For example, the first two shots of your buddy and the board if you take it off auto, manually select the left focus point it would make the subjects sharp. On Auto the camera is just going to guess what to focus on. Alternatively you can just select the middle point (what I do mostly), point it at your buddy/board, hold it down halfway so it focuses, then recompose (so they're not in the middle of the frame) and fire off.
In any event, looks like an awesome time. I am hooked and have thought about going back every day since the season ended.
